National Semiconductor 54AC253 54ACT253 Dual 4-Input Multiplexer with TRI-STATE Outputs Datasheet
National Semiconductor's 54AC253 and 54ACT253 are dual 4-input multiplexers with TRI-STATE outputs. According to the datasheet, the devices select two bits of data from four sources using common select inputs, and each output can be switched to a high-impedance state by a HIGH on its Output Enable input.
The document gives pin names and connection diagrams for DIP, Flatpak and LCC packages, a truth table and logic equations, absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, capacitance values, and physical dimensions for the E20A, J16A and W16A packages.
